Final answer:
A grocery list is not an example of an algorithm, as it is just an itemized compilation of items and does not provide a step-by-step process to follow in order to achieve a particular result as the other options do.
Step-by-step explanation:
Among the options provided, the one that is NOT an example of an algorithm is b) a grocery list. An algorithm is essentially a set of instructions leading to a solution or the completion of a task. Therefore, a recipe to make chocolate chip cookies (a), instructions for changing a flat tire (c), and steps to calculate the amount of paint for painting a room (d) are all examples of algorithms because they provide step-by-step guidance toward achieving a specific result.
A grocery list, on the other hand, is simply an itemized list of ingredients or supplies needed but it does not provide steps or methods to follow for a particular end result, thus it is not considered an algorithm. To provide more context, in the world of computer science, algorithms are vital for developing software and performing functions such as searching data or sorting information.
